SLC25A31 is a gene that encodes a protein involved in the transport of specific molecules across the inner mitochondrial membrane. This protein plays a crucial role in cellular metabolism by facilitating the movement of metabolites, which are essential for energy production and various biochemical processes within cells. Mutations in the SLC25A31 gene can lead to metabolic disorders, particularly affecting the body's ability to process certain nutrients. These disorders can result in a range of health issues, highlighting the importance of this gene in maintaining proper cellular function and overall metabolic health.
